Cleaning plumera leaf stains off tiles

Just a thought - if it contains sodium hypochlorite, my vague memories of schoolboy chemistry make me think that produces hypochloric acid, a weak acid which I'm guessing is the active cleaning agent? Will the bleach dissolve the grout between the tiles, or will that only happen if you use it frequently?

Bleach is strong base.  Not likely to produce an acid.

    The bottle in pic is Hygiene brand laundry bleach. If this is doing the job then pool chlorine will be much more effective and a lot cheaper.
